HEELlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 233,504, dated October 19, 1880.

Application filed February 8, 1879.

To all whom it may concern:

Be it known that I, REUBEN M. HARRISON, of Newark, in the county of Essex andState of New Jersey, have invented an Improvement in Machines for Nailing Heels to Boots and Shoes, of which the accompanying drawings, with the following description, is a specification.

This invention relates to mechanism for nailing the heels of boots and shoes-to attach them to the soles.

My invention in heel-nailing machines consists, essentially, in a last to hold the shoe and a perforated nail-receivin g presser or rest to bear against the outer end of the heel and hold it in place upon the shoe, combined with a removable loading device provided with a sliding bottom to discharge the nails and permit them to drop into the holes of the presser or rest, and a follower provided with drivers to, in its descent, drive the nails from the presser or rest into and through the heel, substantially as hereinafter described.

Figure 1 is a front elevation of my invention with the presser or rest thrown down as it will be when in position upon the heel, the socket part of the carriage or that part which receives the last-extension being in section; Fig. 2, a section on the line as as, representing the presser or rest in top view with the loading device applied; and Fig. 3 is a vertical section of part of the machine, showing the presser and loading device with its bottom plate in position to hold the nails.

The last or jack to has a post or extension, I), which is fitted within a socket, c, (or it might be about a pin,) of a carriage or slide, d, fitted to be moved horizontally in suitable guideways of a plate, 6, an adjustable stop, f determining the backward position of the carriage.

At the upper portion of the machine is a cross-head, g, at the lower end of which is a presser or rest, h, provided with a proper number of openings, 2, for the reception of the nails which are to be driven from the said presser or rest after it shall have been thrown down firmly upon the heel-lift end or outer end of the heel of the shoe, resting as usual on the usual last.

The presser or rest is of sufficient thickness to maintain in upright position the nails to be driven, and the cross-head is depressed to place the rest upon the heel by means, as shown in this instance of my invention, of a foot-lever,

t', connected by links 3, (shown in dotted lines,).

with levers j, one at each side of the frame, the said levers being connected, by means of the links 4, with the ends of the cross-head g, the leverage being sufficient to press the rest it firmly down upon the heel. This lever t is provided with a metallic edge-piece, which, as the lever is depressed, is made to engage with one of the teeth of arack-bar, k, the edge-piece and rack-bar constituting a locking device for the lever, so as to retain the presser or rest in a fixed position when depressed, as described.

Prior to driving the nails from the presser, it is necessary to clamp the heel and heel end of the sole as closely together as possible, and this I accomplish by means of a lifting-screw, l, which, when the carriage is in position, may be elevated and be made to act upon the standard or part of the last to thereby lift it and the heel thereon, and press the heel as firmly and closely as possible between the last and presser or rest.

In this present form of my invention the screw is held in the plate 0, and its head 6 is provided with holes adapted to receive the end of a lever or bar, by which to rotate the screw, as may be desired. At the upper side of this rest I have shown a guideway, 8, which I prefer to employ to guide the loading device which holds and discharges the nails directlyinto the opening in the presser or rest. This loading device is composed of a perforated plate, m, in which the nails are first set up, and of a removable bottom plate, a, (shown in solid black lines in Fig. 3,) upon which the lower ends of the nails rest.

When the loader is placed in position above the rest or presser, so that the ends of the nails in the loader come opposite the holes in the presser, then the removable bottom plate is withdrawn, when the nails are permitted to drop into the holes 2 in the presser, their lower ends resting upon the outer end of the heel. After this the loader is removed from above the presser, and the shaft 0, provided with a cannp, is turned, preferably by means of a clutch and gear, to depress the follower or head 1*, to which are attached the drivers 5, of suitable number and length to drive the nails from the holes I. of the presser or rest 11 into the heel which is to be attached to the shoe held upon the jack.

Suitable springs 0 attached to the crosshead 9 and to the frame of the machine, and another spring, b, about the shank of the head 1', lift the cross-head and head r at the proper time. These springs will preferably be of spiral form.

Upon the under side of the presser I have arranged a clamp or gage,f, to determine the backward position and correct placing of the heel to be applied to the shoe. This gage, shaped to act as a clamp, is shown supported by ears 10 of the presser h, and is made longitudinally adjustable thereon. This gage serves to act against the heel to control its backward position with reference to the nail -driving mechanism, and it also acts against the sides of and holds or clamps the heel while the heel is being seated upon the sole.

Instead of the screw to act upon the lastextension, I may use a wedge or other equivalent device.

The presser and plate m will have the holes for the nails arranged in proper shape to corheel added of usual height will occupy a lower position with reference to the presser h than is shown in the drawings, and the lower edge of the gagef will just touch the quarter respond with the shape of the heel, and the 5 that the bottom of the shoe and last with a 0 of the shoe or the heel end of the sole. The 5 gagefis extended about and so as to act upon i the sides of the heel to be attached.

I claim- In a heel-nailing machine, a. last to hold a shoe, and a perforated nail-receiving presser or rest to bear against the outer end of the heel and hold it in place upon the shoe, com- 1 bined with a removable loading device pro- I vided with a sliding bottom to discharge the I nails therefrom into the holes in the rest, and a follower or head provided with drivers to drive the nails downward into the heel, substantially as described.

5 In testimony whereof I havesigned mynanie I I i I to this specification in the presence of two subscribing witnesses. i REUBEN M. HARRISON. l
